Convergence was written for saxophonist Heidi Radtke Siberz. I was interested in the interaction between the intrinsic qualities of electronic and acoustic mediums. In this piece, I used the electronics and saxophone as equal partners to take turns in background and foreground roles and to create timbral illusions. I also explored the altissimo range (very high notes) on the saxophone, which can provide unique timbral effects and is technically challenging.
There are two main ideas: trills or noodling figurations, and sustained notes. These are mutated into each other throughout the piece. The overflowing of recorded saxophone sounds at the climax is morphed into the live saxophone at the end. Most of electronic sound materials used in the piece are a manipulation of saxophone sounds pre-recorded by Heidi. The piece is dedicated to Heidi, whose passion for new music inspires me.
